Hmm, sounds similar to what I needed done for my application. This is what I came up with, as a function in my gallery model. Maybe you can try and use it for what you need? Will most likely need to change the coding a bit, but it should give you a start :3
Code:
function thumbnail($image, $width, $height, $align='', $master_dim='auto')
{
// Path to main image directory and thumbnail directory
$full_image_directory = '/yourdomain.com/application/assets/img/';
$full_thumbnail_directory = '/yourdomain.com/application/assets/img/thumbs/';
$image_directory = 'application/assets/img/';
$thumbnail_directory = 'application/assets/img/thumbs/';
$thumbnail_folder = $width . '_x_' . $height . '_' . $master_dim . '/';
// Path to image and thumbnails
$image_path = $image_directory . $image;
$thumbnail_path = $thumbnail_directory . $thumbnail_folder;
$thumbnail_path_create = $full_thumbnail_directory . $thumbnail_folder;
$this->create_folder($thumbnail_path);
// Path to image thumbnail
$image_thumb = $thumbnail_path . $image;
// LOAD LIBRARY
$this->load->library('image_lib');
if( ! file_exists($image_thumb))
{
// CONFIGURE IMAGE LIBRARY
$config['image_library'] = 'gd2';
$config['source_image'] = $image_path;
$config['new_image'] = $image_thumb;
$config['maintain_ratio'] = TRUE;
$config['height'] = $height;
$config['width'] = $width;
$config['master_dim'] = $master_dim;
$this->image_lib->initialize($config);
$this->image_lib->resize();
$this->image_lib->clear();
}
else
{
// Pull the create date from the image and store to a variable
$original_create_date = filemtime($image_path);
// Pull the create date from the thumbnail image and store to a variable
$thumbnail_create_date = filemtime($image_thumb);
// Check the dates. If the original image create date is greater than the thumbnails create date, update the thumbnail image. If not, simply echo out the thumbnail.
if ($original_create_date > $thumbnail_create_date)
{
// CONFIGURE IMAGE LIBRARY
$config['image_library'] = 'gd2';
$config['source_image'] = $image_path;
$config['new_image'] = $image_thumb;
$config['maintain_ratio'] = TRUE;
$config['height'] = $height;
$config['width'] = $width;
$config['master_dim'] = $master_dim;
$this->image_lib->initialize($config);
$this->image_lib->resize();
$this->image_lib->clear();
}
}
return '<img align="' . $align . '" src="' . base_url() . $image_thumb . '" />';
}
function create_folder($folder)
{
if (! file_exists($folder))
{
$this->load->library('ftp');
// Create the directory and CHMOD it to 777.
$this->ftp->connect();
$this->ftp->mkdir('yourdomain.com/'.$folder, DIR_WRITE_MODE);
$this->ftp->close();
}
}
